IPC: G02F1/313
Filed: 1981-03-25
Abstract: PURPOSE:To increase the selecting performance of wavelength, by controlling the refractive indexes of two sets of optical waveguides formed on an electro- optical substrate via a grating electrode, a control electrode, an auxiliary electrode, etc. CONSTITUTION:The optical coupling guidewaves 12 and 13 are formed on an optical substrate 11 of LiN6O3, etc. by the Ti diffusion, etc. A buffer layer 14 is coated by the Al vapor deposition, etc. on the substrate 11 opposite to plural bar type grating electrodes 15 and the waveguide 12 which are opposite to the waveguide 13. The layer 14 is made of SiO2, etc. and contains a control electrode 16 forming partially a grating electrode, an auxiliary electrode 17, etc. The refractive index of the waveguide 13 is changed periodically with the voltage applied via an electrode of the grating constitution. Thus the waveguides 13 and 12 are firmly coupled optically to each other. Furthermore the electric field is variably controlled via the electrode 16 and 17 to vary the constant of transmission. As a result, the matching of phase becomes easy and accurate between the waveguides 12 and 13 to each wavelength. Thus the continuous coupling is carried out to an optional center wavelength to increase the selecting performance of wavelength.

Title: Magnetic recording and reproducing device
Inventor: KATAGIRI TOSHIYUKI
IPC: H04N9/83
Filed: 1986-02-27
Abstract: PURPOSE:To prevent the degrading of definition of a reproduced picture due to the attenuation of the lower sideband wave by making the characteristic impedance of a high-pass filter circuit to extract an FM luminence signal mismatching the output impedance of a reproducing amplifier circuit to generate a filtering characteristic curve which ascends in the vicinity of the cut-off frequency of the HPF circuit. CONSTITUTION:Of a magnetic recording and reproducing device 11, the high-pass filter circuit 13 is provided between the output resistor R of a transistor Qb and a limiter circuit 7 that are in the reproducing amplifier 12. The characteristic impedance Z of the high-pass filter circuit 13 is set in a sufficiently large value in comparison with the output impedance Z of the circuit 12. Since a signal reflects based on the mismatching between the impedances z and Zo, a standing wave is generated to make ups and downs in the frequency characteristic. The overall filtering characteristic is such that a round-top peak is formed in the vicinity of the cut-off frequency f0 with which the part other than the central part of the lower sideband wave of an FX brightness signal overlaps. As a result, the attenuation of the lower sideband of the said signal at the time of separating a brightness/color signal, can remarkably avoided, and accordingly the definition of a reproduced picture can be upgraded.

Title: Method for adding special element in degassing stage of vacuum degassing device
Inventor: NAMURA NATSUKI
IPC: C22C33/04
Filed: 1984-03-06
Abstract: PURPOSE:To enable use of the oxide of special elements such as Nb, V, Ti and B obtainable more inexpensively than ferroalloy by adding said elements in the form of oxide to an RH degassing device and making use of the low CO partial pressure in the degassing stage. CONSTITUTION:The deoxidizing power of carbon increases to the power stronger than the deoxidizing power of alloy elements having powerful deoxidizing powder in a vacuum in the degassing stage where the gaseous pressure is extremely low. Oxide of Nb, V, Ti and B is thereupon added to the degassing stage under <=10Torr of an RH vacuum degassing device. The amt. of the inert gas to be blown is made smaller than in the ordinary degassing stage to add said oxide so that the reflux rate of the molten steel to be treated in the degassing device is made lower than the rate in the ordinary degassing opperation. The above- described oxide of Nb, etc. is thus reduced by carbon and a considerable reduction in cost is attained.

Abstract: PURPOSE:To lengthen the life of a heat-sensitive head by equalizing the heating frequency of a heating element by switching the print starting direction of a ticket face pattern to the opposite direction in a heat-sensitive printer to print a paper slip, such as ticket, etc. CONSTITUTION:In a heat-sensitive printer in which a heat-sensitive head 1 is provided and a platen roll 2 is provided in the face of the heat-sensitive head 1, a heat-sensitive paper 4 sent out from a rolled heat-sensitive paper 3 is brought into contact with the heater of the heat-sensitive head 1 and sent to the direction of arrow A, while a heating element in the heater is selected in terms of picture element and energized by application of a voltage. Then, a ticket face pattern for railroad ticket, etc., is printed on the heat-sensitive paper 4, and the heat- sensitive paper 4 is cut off by a cutter blade 5 for selling. At this time, if the same pattern of the ticket 6a is used at all times, the heating frequency of the heating element is dispersed irregularly. For this reason, like the ticket 6b, the print starting direction is reversed in order to equalize the heating frequency and also to lengthen the life of the heating element.

Title: Power unit
Inventor: OKAMOTO KAZUYA
IPC: H02M3/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To materialize correct current feedback without completely insulating all of an auxiliary power unit, an external i/o signal circuit, etc., by connecting a current suppressive means between the line at the earthed potential on input side of a latter-stage power source and the line at the earthed potential on output side. SOLUTION: A former stage power source 10 generates middle voltage V1 (for example, 48V) of DC, with commercial power as input. The output voltage of the previous-stage power source 10 becomes the input voltage of a latter-stage power source 10, and generates output voltage V2 (for example 5V) of DC. GND1 is at earthed potential (0V) of the former-stage power source 10, and GND2 is at earthed potential (0V) of the latter-stage power source 20. One end of a resistor 26 is connected with the line of 0V on output side of a noninsulation type of auxiliary power source 24, and for the other end, a power control circuit 25 connects it to the junction with the 0V line on output side of the latter-stage power source 20d, or to the 0V line closer to the auxiliary power source than that.  Hereby, the output current of the former-stage power source 10 can be fed back to GND1 along a correct course.

Title: Magneto-resistance effect type magnetic head
Inventor: TAKAGI HITOSHI
IPC: G11B5/39
Filed: 1983-03-17
Abstract: PURPOSE:To constitute a titled head so that a shape demagnetizing field in the track width direction is small even in case when the track width is narrowed, and also the resistance value of a magneto-resistance effect element does not drop, by constituting so that a length of a ferromagnetic thin film is larger than a track width of a head, and also a width of a part of the ferromagnetic thin film opposed to a track is larger than a width except the track width. CONSTITUTION:A magneto-resistance element 11 consisting of a ferromagnetic thin film consists of a part 11a corresponding to a track and a part 11b which is not opposed to the track. A length l2 of the magneto-resistance element 11 is larger than a track width l1. Also, a width w2 of 11a is larger than a width w1 of 11b. A shape demagnetizing field is in inverse proportion to an element width; therefore, the demagnetizing field in the part which is not opposed to the track can be made much larger than the demagnetizing field in the part 11a opposed to the track, and it can be realized that the bias magnetic field is scarcely applied at the effective time to the element of the part which is not opposed to the track. A current (j) flows through the part of the width w1 of the part which is not opposed to the track, and a resistance value of the MR element does not drop even if w2 is set larger than w1 in the part 11a opposed to the track.
